JOHN SLATER, OF EAsT HAM, ENGLAND, ASSIGNOR To MABIE ToDD AND BARD, onNEW YORK, N. Y.

MEANS FOR ATTACHlNG CAPS T FOUNTAIN OR OTHER PENS, 8L0.

SEECIFICATION forming part of Letters Patent No. 716,489, dated December23, 1902. Application filed September 15,1902- Serial No. 123,553. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN SLATER, mechanic, of 23 Milton avenue, EastHam, county of Essex, England, have invented certain new and usefulimprovements in means for attaching caps to fountain or other pens or topencils or the like or for attaching other sections or parts together,of which the following is a specification.

This invention has reference to means for attaching caps to fountain andother pens or to pencils or the like or for attaching other sections orparts together. It has been more particularly designed for attachingcaps to fountain-pens adapted to be suspended from achatelaine,waist-belt, or other article of dress;

but, as will be well understood, it can be employed with advantage forattaching pointguards to pencils or generally for connecting a tubularor partly tubular section to any part or section to which it may bedesired to attach the same.

I will describe the invention as applied to a fountain-pen of thesuspended type, and its 2 5 application to other articles will then bereadily understood.

With fountain-pens of the kind in question it is usual to suspend thecap by means of a chain or other attachment to the dress and to 0connect the pen to the cap by means of a bayonet or other simple joint.It has been found in use that the pen is liable to become detached and10st, owing to carelessness in inserting it in the cap after use or fromother 3 5 cause. By my invention this disadvantage is overcome and thecap and holder are securely locked together, while being adapted to bereadily disconnected when desired.

According to this invention in one form 40 thereof I provide thepen-section at a suitable point with a pin, and I form the lower edge ofthe cap with a longitudinal slot adapted to give passage to said pinwhen the cap is placed over the pen. Upon the lower end of the cap Imount a band or collar, which is free to be turned around or backwardand forward on the cap in order to lock or release the said pin, ashereinafter described. The inner face of this band or collar is formedwith a groove or recess extending longitudi-' nally of the pen-barreland of sufficient depth to allow the pin to travel therein when theparts are to be connected or disconnected, while the collar has a rotarymotion which serves to move the groove out of alinement with the pin andlock the parts firmly together, with the pin at the inner end of theslot in the cap. The collar may be attached to the cap in any convenientway. A transverse slot of suitable length may also be formed in the wallof the collar. A pin on the cap works in this slot, the ends of the slotacting as stops to this pin and limiting the turning motion ofthe collarin either direction. The length of the transverse slot is preferablysuch that when the collar is turned in the one direction until the pinon the cap strikes one end of its slot the internal groove of the collarcoincides with the longitudinal slot in the cap, and the pin on thepen-section can be passed into or out of said slot. On the other hand,by turning the collar in the other direction the groove and slot aremoved out of coincidence, and the collar serves to securely lock the pinon the pensection in the slot of the cap. i

The accompanying drawings illustrate a pen-section and cap constructedand adapted to be locked together as above described.

In the drawings, Figure 1 is a central lon- 8o gitudinal section throughthe pen-section and cap, the nib and ink-feeding members being omittedfor the sake of simplicity. The pensection is shown as inserted in thecap, with the locking-collar in the position in which its groove givespassage to the pin on the pensection. Fig. 2 is a transverse section online A B of Fig. 1. Fig. 3 is acorresponding section to Fig. 2, butshowing the locking-collar turned to lock the pensection and captogether.

o'. is the pen-section, adapted to be screwed, as usual,into thereservoir or holder of the pen. (Not shown.) I) is the pin carriedthereby, as above described.

c is the cap, and d the longitudinal slot therein adapted to givepassage to the pin b when the pen-section is inserted in the cap.

6 is the locking-collar, mounted on the cap 0 and free to turn thereonwith a suitable de- I00 gree of friction to prevent its slipping aroundaccidentally. The motion of the collar e is limited by the pin f on thecap working in the transverse slot 9 of the collar. The inner face ofthe collar is formed with a longitudinal groove h-t'. e., longitudinalwith reference to the pen-section or barrel and cap adapted to bebrought into coincidence with the slot 01 by turning the collar e, thisgroove it being of sufficient depth to permit the pin 1) to pass throughsame to the rear of the collar c or to be withdrawn, as required. Thelength of the slot g is such that when the collar e is turned in the onedirection until the pin f strikes one end of this slot the groove hcoincides with the slot d, and the pin 1) can pass through said slot andgroove to enable the pen-section to be introduced into or removed fromthe cap. When the pen-section has thus been introduced into the cap, thecollar is turned in the opposite direction, whereby the groove h andslot d are moved out of coincidence, and the collar securely locks thepin b of the pen-section at the end of the slot dot the cap.

What I claim, and desire to secure by Letters Patent, is

1. Means for attaching caps to fountain and other pens, or to pencils,or for securing tubular or partly tubular sections or parts to otherparts or members, comprising the combination of a pin on the one part tobe connected, a longitudinal slot in the other part and a collar havinga longitudinal recess therein adapted by turning said collar to bebrought into and out of coincidence with said slot, whereby when saidslot and recess are in coincidence said pin can be passed therethrough,and when said collar is turned to move said slot and recess out ofcoincidence, said pin can be locked in said slot by said collar,substantially as described.

2. Meansfor attachingcaps to fountain and other pens, or to pencils, orfor securing tubular or partly tubular sections or parts to other partsor members, comprising the combination of a pin on the one part to beconnected,

a longitudinal slot in the other part, a collar on said last-mentionedpart having a longitudinal recess adapted, by turning said collar, to bebrought into and out of coincidence with said slot, whereby when saidslot and recess are in coincidence said pin can be passed therethrough,and when said collar is turned to move said slot and recess out ofcoincidence the pin can be locked in said slot by said collar, and apin-and-slot connection between said collar and the part on which it ismounted, and serving to limit the turning motion of said collar,substantially as described.

3. Means for attaching caps to fountain and other pens, or to pencils,or for securing tubular or partly tubular sections or parts to otherparts or members, comprising the combination of a pin on the one part tobe connected and a longitudinal slot in the other part, a collar on saidlast-mentioned part having a longitudinal recess adapted, by turningsaid collar. to be brought into and out of coincidence with said slot,whereby when said slot and recess are in coincidence said pin can bepassed therethrough and when said collar is turned to move said slot andrecess out of coincidence the pin can be locked in said slot by saidcollar, and a pin-and-slot connection between said collar and the parton which it is mounted and serving to limit the turning motion of saidcollar, the relative arrangement of said pin-and-slot connection andsaid first-men tioned slot being such that when the pin of thepin-and-slot connection is in its one extreme position said longitudinalslot coincides with the recess in the collar, substantially asdescribed.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
